BUTTON-STITCHING MACHINE.

T 0 all 10 hom it may concern Be it known that I, J OHN RUssELL, of 185 Garrioch Road, Maryhill, Glasgow, Scotland, have invented certain new and useful Improvements in and Connected with Button-Stitching Machines, of which the following is a specification.

My invention relates to improvements in spacing devices for use on button stitching machines.

The device is of the kind by which the spaces from button to button in the process of stitching on to a garment can be regulated by placing the first button after it has been stitched on to the garment against a guide, the distance from needle to guide determining the distance between each button and the next. The same operation is performed for each succeeding button.

In carrying out my invention, I provide a suitably shaped adjustable guide-plate to which is suitably fixed a divided scale or scales for determining the length of the spacings and one or more bent arms with pointers moving over said scale or scales, the said arms being provided with a slot for holding or retaining the last stitched button while the stitching on of the next button is in progress. There is also a guideway in which the said arms move and a clamping screw for fixing said arms in the desired position. The guide-plate is suitably at tached to the sewing machine.

In order that my invention may be properly understood. and readily carried into effect, I have hereunto appended one sheet of drawings, of which Figure 1 is a plan view of the guide attachment, scale and pillars mounted on a button stitching machine made in accordance with and embodying my invention.

Figure 2 is a front view thereof, and

Figure 3 is an end view of the guide attachment, scale adjustment, and a pillar upon which said attachment is carried, which pillar is suitably fixed to the sole plate of a button stitching machine, all hereafter more fully referred to and described.

l/Vith reference to the drawings, the guide attachment A and scales N and B are carried upon pillars C, D, disposed on each side of the needle bar E said pillars being secured to the sole plate X of the machine.

The attachment consists of a bent arm A and pointer F. The bent arm has a hori- Specification of Letters Patent.

zontal rear extension G which is adapted to slide within the space or guide-way H formed by two parallel bars of metal I, J, attached together at the middle and ends thereof, as seen in Figure 2, by distance pieces K, L, M. The bar J has scales N and B, Figure 1, cut or engraved upon it.

The arrangement shown in the figures is a duality of the parts just described and consists of two bent arms A and A two pointers F, F and two scales B and N commencing at zero in the centre, as seen in Figure l. The bent arms A and A are adapted tobe moved the one A alon the surface of the scale B and the other A along the surface of the scale N and clamped by nuts S and S to any desired position after the adjustment has been made. Said bent arms are provided each with a slot 0. This two fold arrangement is adopted in order that button stitching may be performed by moving the cloth either from the right-hand side or left-hand side of the needle bar. The space between the buttons P, Q, on the material R to be stitched having been predetermined by the distance between the button holes, the pointer is moved in unison with such length and the arm locked in that position. The slot 0 in the arm A has a spring T stretched across it, such such spring arrangement compensating for undue tension on the cloth which otherwise would be caused by the movement of the but ton holder attachment, already forming part of the machine, from one hole in the button to the opposite one.

Claim.

In combination with the sole plate and needle bar of a button stitching machine, a guide attachment comprising pillars secured to the sole plate at points spaced from opposite sides of the needle bar, a guide bar secured on said pillars, said bar having scales, bent arms slidably secured to said guide bar and having pointers for movement over the scales, said arms-having slots for the holdingor retaining of the last stitched on button during the operation of stitching on the next, and clamping means to secure the arms'in adjusted position.

In witness whereof I affix my signature in presence of a witness.
